The agency that handles the registration of patents and trademarks in the U.S. today issued a further request from the offices of Apple. The new record of Apple's patent provides a system for inductive charging of the battery through the iPad Smart Covers. For this, however, these cases would still have an integrated battery to transfer power to the tablet when needed. Thus, the Smart Cover does not just protect the device, it would also serve as a kind of auxiliary battery for the tablet, increasing the time taken away from charger.

Accurate and reliable techniques for wirelessly powering a tablet device are disclosed - says the patent.

Still, there is more specific information about how the cover would be charged. However, we can expect that to happen through their iPad, when it is plugged in, or a specific charger. Another question is regarding the Smart Cover is inductive on weight. If it will have an integrated battery and a system to transfer energy without wires, it is expected that the device is thicker and heavier than the current one.

This could actualy point a system to charge all iGadgets at once.

With the publication of the patent, Apple fans have begun to imagine how it would be more practical to charge all their iGadgets. Thus, with possible iPhones, iPods and other devices with inductive charging technology, you could put them all on top of the iPad with the new cover and charge them all at once, saving wires and plugs.

As this is just a patent, we can not say that this device will now follow the next version of the tablet. Other than that, until now there was no confirmed indications of a possible iPhone or other device device with this technology, which can end up with the theory of collective charging up the tablet.
